Write Cycles Device Operation CLOCK and DAA RANIION: he DA pin is normally pulled high with an external device. Data on the DA pin may change only during CL low time periods (refer to Data Validity timing diagram). Data changes during CL high periods will indicate a start or stop condition as defined below. AR CONDIION: A high-to-low transition of DA with CL high is a start condition which must precede any other command (refer to tart and top Definition timing diagram). OP CONDIION: A low-to-high transition of DA with CL high is a stop condition. After a read sequence, the stop command will place the EEPROM in a standby power mode (refer to tart and top Definition timing diagram). ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the EEPROM in 8 bit words. he EEPROM sends a zero to acknowledge that it has received each word. his happens during the ninth clock cycle. ANDBY MODE: he A24C02A/04A/08A features a low power standby mode which is enabled: (a) upon power-up and (b) after the receipt of the OP bit and the completion of any internal operations. MEMORY REE: After an interruption in protocol, power loss or system reset, any 2-wire part can be reset by following these steps:(a) Clock up to 9 cycles, (b) look for DA high in each cycle while CL is high and then (c) create a start condition as DA is high. 4 A24C02A/04A/08A

7 A24C02A/04A/08A Device Addressing he 2K, 4K and 8K EEPROM devices all require an 8 bit device address word following a start condition to enable the chip for a read or write operation (refer to Figure 1). he device address word consists of a mandatory one, zero sequence for the first four most significant bits as shown. his is common to all the EEPROM devices. he next 3 bits are the A2, A1 and A0 device address bits for the 2K EEPROM. hese 3 bits must compare to their corresponding hard-wired input pins. he 4K EEPROM only uses the A2 and A1 device address bits with the third bit being a memory page address bit. he two device address bits must compare to their corresponding hard-wired input pins. he A0 pin is no connect. he 8K EEPROM only uses the A2 device address bit with the next 2 bits being for memory page addressing. he A2 bit must compare to its corresponding hard-wired input pin. he A1 and A0 pins are no connect. he eighth bit of the device address is the read/write operation select bit. A read operation is initiated if this bit is high and a write operation is initiated if this bit is low. Upon a compare of the device address, the EEPROM will output a zero. If a compare is not made, the chip will return to a standby state. Write Operations BYE WRIE: A write operation requires an 8 bit data word address following the device address word and acknowledgement. Upon receipt of this address, the EEPROM will again respond with a zero and then clock in the first 8 bit data word. Following receipt of the 8 bit data word, the EEPROM will output a zero and the addressing device, such as a microcontroller, must terminate the write sequence with a stop condition. At this time the EEPROM enters an internally-timed write cycle, t WR, to the nonvolatile memory. All inputs are disabled during this write cycle and the EEPROM will not respond until the write is complete (refer to Figure 2). PAGE WRIE: he 2K EEPROM is capable of an 8-byte page write, and the 4K and 8K devices are capable of 16- byte page writes. A page write is initiated the same as a byte write, but the microcontroller does not send a stop condition after the first data word is clocked in. Instead, after the EEPROM acknowledges receipt of the first data word, the microcontroller can transmit up to seven (2K) or fifteen (4K, 8K) more data words. he EEPROM will respond with a zero after each data word received. he microcontroller must terminate the page write sequence with a stop condition (refer to Figure 3). he data word address lower three (2K) or four (4K, 8K) bits are internally incremented following the receipt of each data word. he higher data word address bits are not incremented, retaining the memory page row location. When the word address, internally generated, reaches the page boundary, the following byte is placed at the beginning of the same page. If more than eight (2K) or sixteen (4K, 8K) data words are transmitted to the EEPROM, the data word address will roll over and previous data will be overwritten. ACKNOWLEDGE POLLING: Once the internally-timed write cycle has started and the EEPROM inputs are disabled, acknowledge polling can be initiated. his involves sending a start condition followed by the device address word. he read/write bit is representative of the operation desired. Only if the internal write cycle has completed will the EEPROM respond with a zero allowing the read or write sequence to continue. Read Operations Read operations are initiated the same way as write operations with the exception that the read/write select bit in the device address word is set to one. here are three read operations: current address read, random address read and sequential read. CURREN ADDRE READ: he internal data word address counter maintains the last address accessed during the last read or write operation, incremented by one. his address stays valid between operations as long as the chip power is maintained. he address roll over during read is from the last byte of the last memory page to the first byte of the first page. he address roll over during write is from the last byte of the current page to the first byte of the same page. Once the device address with the read/write select bit set to one is clocked in and acknowledged by the EEPROM, the current address data word is serially clocked out. he microcontroller does not respond with an input zero but does generate a following stop condition (refer to Figure 4). RANDOM READ: A random read requires a dummy byte write sequence to load in the data word address. Once the device address word and data word address are clocked in and acknowledged by the EEPROM, the microcontroller must generate another start condition. he microcontroller now initiates a current address read by sending a device address with the read/write select bit high. he EEPROM acknowledges the device address and serially clocks out the data word. he microcontroller does not respond with a zero but does generate a following stop condition (refer to Figure 5). EQUENIAL READ: equential reads are initiated by either a current address read or a random address read. After the microcontroller receives a data word, it responds 7

8 with an acknowledge. As long as the EEPROM receives an acknowledge, it will continue to increment the data word address and serially clock out sequential data words. When the memory address limit is reached, the data word Figure 1. Device Address address will roll over and the sequential read will continue. he sequential read operation is terminated when the microcontroller does not respond with a zero but does generate a following stop condition (refer to Figure 6). 2K A 2 A 1 A 0 R/W MD LB 4K A 2 A 1 P0 R/W 8K A 2 P1 P0 R/W Figure 2.
